can you please post the contents of the rm.log file (user/.RapidMiner5/rm.log) after you restarted RapidMiner and tried to open an Import wizard via "File" -> "Import Data" -> "Import Excel Sheet..."?

Regards,Marco

The following represents me launching RM, starting a New Process, clicking each of the three options in turn, then shutting down. Must of the content appears to be generated by the inability to contact the update server, it being blocked by the firewall:

I don't see anything in your log which would indicate a problem which might cause this issue, which is rather strange. I also could not reproduce the issue on any test machine here, everything works fine, so this might be a little bit tricky to figure out. Can you please start the RapidMinerGUI.bat script from the command line (found inside the RapidMiner5/scripts folder), and paste the whole output here? You can copy & paste from the windows command line via rightclick -> select all and then leftclick in the upper left corner on the icon, go to Edit and then select copy.

Regards,Marco

Are you from a scientific background and want to use RapidMiner Studio 6? Check out our new RapidMiner Academia program!

I have encountered the same problem as colmoni, but the difference is that I'm running Mac OSX. When starting the Java 7 download I get the following message:

Quote

"If you download Java 7, you will not be able to run Java content in Chrome and will need to use a 64-bit browser (such as Safari or Firefox) to run Java content within a browser. Additionally, installing Java 7 will disable the ability to use Apple Java 6 on your system".

It will tell you if you have java 1.7. If you do you should see Java in your System Preferences.Click on Java tab and "View..."Under Path you'll see where Java 7 is installed.Edit scripts/RapidMinerGUI script to hardcode JAVA_HOME to point to the location of Java 1.7

It should resolve your issue with RapidMiner and will not affect anything else.
